I had the first version earlier of this grip but I sold it since i did not need it that much and then there was problems with live view, it dropped the connection all the time. Now my USB port is broken since I tripped on the wire and fixing it cost almost as much as an WFT e 4, but I do need the live view some times on my lap top. Has anyone got the live view working with this new version without dropped connection? Or do you know if the usb-port in the grip can be used to shoot tethered or is it just for an external drive? My laptop is a about 2 y.o. MBP with the latest OSX in it.
